Answer: The zeros of the quadratic function are: 5/2+(1/2)*sqrt(31), 5/2-(1/2)*sqrt(31)
Step-by-step explanation:
Y=(3/4)(x)+(19/4)
5=(3/4)(x)+(19/4)
(1/4)=(3/4)(x)
x=(1/3)
And what else is in the problem ??????
Answer: Create intervals, then count the number of countries that fall in each interval.
When you create a frequency table, you have set intervals. In this case, our small number is close to 0 and our largest number is 4.5. We could create an interval for each number. Then, count the number of countries in each.
It would look like:
Interval Frequency
0-0.99 1
1-1.99 5
2-2.99 5
3-3.99 2
4-4.99 1
